Image forming apparatus for determining a difference in lightness between colors in toner image forming units
Abstract:
An image forming apparatus includes a transfer member, first transfer units, and second transfer units. Images of reference colors and other colors are transferred onto the transfer member being rotated. The first transfer units each transfer the image of a corresponding one of the reference colors. The second transfer units disposed upstream of the first transfer units in a rotational direction of the transfer member each transfer the image of a corresponding one of the other colors. The image of one of the reference colors is transferred by one of the first transfer units disposed most upstream. The other colors include at least one color of lightness lower than lightness of the one of the reference colors of the image transferred by the one of the transfer units. The highest-lightness image among the other colors is transferred by one of the second transfer units disposed most downstream.
